126 7 Maintenance
• Do not reuse print cartridges that have been removed from the printer. Doing so may 
cause degradation of print quality, or the toner may spill onto print jobs.
• Do not shake or pat the removed print cartridges after you remove it. The remaining toner 
may spill out.
• Although the toner is not harmful to the body, wash it off immediately if your hands or 
clothes are stained with it.
